2002 wrx
my heater blower works only in 4th position, doesn't go on in 1st, 2nd or 3rd.
Talked to an electrician, he said that there is a thing beside the blower motor on the passenger side, behind the glove box held in place by two little screws, has a brown connector attached to it, he said that I need to unscrew the two screws and replace that thing. He said it burned out. I took it out yesterday, and it seemed fine. It looks like credit card with a connector on the bottom side, when you take it out of the heater assembly. I don't think there is anything wrong with this thing. Any ideas?
